SPECIFICATION forming part of Letters Patent No. 540,240, dated June 4,1895. Application filed April 13,1894. Serial No. 507,359. (No model.)

To all whom it may concern.-

Be it known that I, TALBOT O. DEXTER, of Fulton, in the county ofOswego, in the State of New York, have invented new and usefulImprovements in Paper-Folding-Machine Attachments to Printing-Presses,of which the following, taken in connection with the accompanyingdrawings, is a full,clear, and exact description.

This invention relates to the class of papertransferring apparatus whichare placed between the delivery end of a printing press and apaper-folding machine and convey the paper by means of traveling endlesstapes and are removable from their operative positions to allow them tobe used interchangeably with a fly which simply deposits the pilewithout folding the sheets.

For exemplification of the application of my present invention to theaforesaid papertransferring apparatus, I have shown it in connectionwith the two apparatus for which I have obtained Letters Patent of theUnited States Nos. 505,509 and 506,392. In these as well as in otheranalogous paper-transferring apparatus placed removably between theprinting press and folding machine, the paper-conveying tapes of saidapparatus are caused to hang loosely on their carryingrollers when theapparatus is removed from its operative position, and in this conditionthe tapes are liable to become tangled, and the operation of replacingthe apparatus in its operative positionbetween the printing press andfolding-machine is on that account slow and tedious, and in case thetapes have been exposed to a humid atmosphere, it is very difficult toproperly adjust to their requisite operative position the brackets whichsupport the tapecarrying rollers, owing to the increased tension of thetapes shortened by the moisture.

The purpose of my present inventionis to afford means to allow theaforesaid brackets to be mounted on their supports so as to hold thetapes sufficiently slack to allow them to be examined and adjusted totheir respective lineal positions and subsequently adjusted to tightensaid tapes; and to that end the invention consists in the combinationwith a paper-transferring apparatus equipped with paper-conveying tapes,of brackets supporting the tape-carrying rollers mounted on theirsupports adjustably on lines parallel with the tapes, and leversfulcrumed on said supports and connected to the aforesaid brackets formoving the same to their requisite positions, as hereinafter more fullydescribed and set forth in the claims.

In the annexed drawings, Figure l is a side elevation of my improvementsapplied to a paper-folding-machine attachment for which I have obtainedLetters.Patent No. 506,392, dated October 10, 1893. Fig. 2 is anenlargedside view ofthe adjustable bracket which carries theupper tape-rollers.Fig. 3 is an enlarged transverse section on line XX in Fig. 1. Fig. 4 isa sideview of the attachment of the paper-transferring apparatus to aprinting-press shown in my Letters Patent No. 506,392, dated October 10,1893, embodyingv my present invention. Fig. 5 is an enlarged side viewof the same, and Fig. 6 is a detached plan view of the adjustablesupport of the roller-supporting bracket.

Similar letters of reference indicate corresponding parts.

Referring to Figs. 1, 2, and 3 of the drawings, -O represents one of thesupporting bars of the paper-transferring apparatus placed removablybetween the delivery end B of the printing machine and receiving-bconnected to the bracket engages one of a plurality of sockets --0tinthe stationary plate and retains the bracket in its desired position.

One of the objects of my present invention is to facilitate theattachment and detachment of the bracket I- to and from the bar C andfor that purpose I mount on said bar a longitudinally adjustablemetallic bar D- locked in its adjusted position by the spring depressedpin b connected to said bar and passing through the same and into one ofa plurality of sockets formed in the main bar O- as shown in Fig. 3 ofthe drawings. The upper end of this supplemental bar is formed with anose or upward projecting tongue tleaving a recess t'- under it. Uponsaid supplemental bar is mounted the bracket I- the upper end of thebase of which is formed with a downwardly and rearwardly projecting hook--h which engages the ton gue-t. Said tongue and hook being very muchshorter than the plate and grooved flanges heretofore em ployed forretaining the bracket on the bar, greatly facilitates the attachment andremoval of the bracket when desired.

To sustain the bracket I and supplemental bar D laterally upon the mainbar --O-, I attach to the supplemental bar metal straps cc which embracethe main bar so as to prevent the supplemental 'bar from being liftedfrom the main bar by the strain of the tapes. Said straps extend upwardfrom the supplemental bar and embrace the sides of the bracket. Thelower end of the base of the bracket is formed with a rearwardlyprojecting heel -d across the top of which bears a pin eattached to thetwo straps --c at opposite sides of said heel, said pin serving toretain the lower end of the bracket down upon the supplemental bar. Thebracket in this caseis thus mounted on the primary supporting bar -Oadjustably on a line parallel with the tapes by medium of thesupplemental bar D-.

To facilitate the operation of pushing the bracket I toward the upperend of the bar O- so as to tighten the tapes, I pivot to said bar alever Z- and connect said lever with the supplemental bar D by a stiffstrap -Z'- pivotally connected to said parts. By raising the pin bout ofthe socket a and pushing upwardthe free end of the lever thesupplemental bar D- with the bracket I riding thereon is convenientlypushed toward the upper end of the bar O, and is subsequently retainedin its adjusted position by the pin -bdropping into one of the sockets--a.

When my present invention is to be applied to the bracket-support shownin Figsnl and 5 of the drawings, I mount the supplemental bar D- on thehorizontal plate -O which is supported on the arm A- suspended from thefeedrboard of the press and is provided with the sockets a-a-in its topas shown in Fig. 6 of the drawings.

The connection of the supplemental bar D to the plate (3 issubstantially like the connection of said bar to the main-supporting barO hereinbefore described. The lever I- in this case is fulcrumed on theplate O-- and connected to the supplemental bar -D by the strap Z andthe adjustment of the supplemental bar with the bracket riding thereonis effected by raising the locking pin b and manipulating the lever I inthe manner hereinbefore described.

What I claim as my invention is 1. In a paper-transferring apparatusplaced removably between the delivery end of a printing press andreceiving end of a foldingmachine, an adjustable tape-roller supportconsisting of a bar or plate supported in proximity to the aforesaid endof the printing press, a supplemental bar mounted longitudinallyadjustable on said bar or plate and provided with a forwardly projectingtongue on its front end, the tape-roller supporting bracket mountedremovably on said supplemental bar and provided with a hook engaging theaforesaid tongue, guides sustaining the supplemental bar and bracketlaterally upon its aforesaid bar or plate, a lever fulcrumed on the baror plate, and a stifi strap connecting the lever to the supplemental barsubstantially as and for the purpose set forth.

2. In a paper transferring apparatus equipped with paper-conveying tapesand placed removably between the delivery end of a printing press andpaper-folding machine, the combination of the main supporting bar orplate provided with sockets act, the supplemental bar -D' mountedmovable longitudinally on said supporting bar or plate and provided withthe tongue t on its front end, the bracket -I- provided with the hook -hand the heel d, the straps cc attached to the supplemental bar andsustaining the same and bracket laterally upon the main support, the pin-ebearing on the heel -d and connected to the straps at opposite sidesthereof, the spring-actuated locking pin b connected to the supplementalbar, the lever Z fulcrumed on the main support, and the strap Zconnecting the lever to the supplemental bar as set forth and shown.

In testimony whereof I have hereunto signed my name this 2d day ofApril, 1894.
